Revisited the line features exercises, with the more complex cones/lines maps.
Then we introduced Grid References by using a simple grid of cones in a large square. Each person was given a coordinate to stand at, then they were checked when everyone was in the right place. Adults got this quickly, kids took a little longer. This was repeated.
Adults then spent some time finding places on an OS map using Grid References, while the kids did a memory game with O symbols and photos of the features.
Finished with a cones/line feature exercise using this map. This was very simple to set up and allowed for 8 courses from 2 separate starts. It uses very simple lines to allow for some basic navigation.
The full OCAD for this exercise is here.
A good session, with lots of variety.
